This article aims at submitting a reflection on the universal presuppositions of human culture proposed by Freud, as a prop for analyzing presuppositions of organizational culture according to Schein. In an article published in 1984, the latter claims that in order to decipher organizational culture one cannot rely upon the (visible) artifacts or to (perceptible) values, but should take a deeper plunge and identify the basic assumptions underlying organizational culture. Such pressupositions spread into the field of sttudy concerning the individual inner self, within the sphere of Psychoanalysis. We have therefore examined Freud's basic assumptions of human culture in order to ascertain its conformity with the paradigms of organizational culture as proposed by Schein.
